c# - UInt32.TryParse() 十六进制数不工作

Question

出于某种原因，以下 C# 控制台程序总是输出:

32
False
wtf=0

我做错了什么？

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Globalization;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(Convert.ToUInt32("0x20", 16));
            UInt32 wtf = 0;
            Console.WriteLine(UInt32.TryParse("0x20",
                              NumberStyles.HexNumber, // I've tried also AllowHexSpecifier
                              CultureInfo.InvariantCulture,  // I've also tried CurrentCulture
                              out wtf));
            Console.WriteLine("wtf={0}", wtf);
        }
    }
}

您需要删除“0x”前缀。请看this blog entry
